Answers
Answer:
Meiosis is associated with the haploid number of chromosomes.
Meiosis is a specialized process of cell division in which a diploid cell (cell with two sets of chromosome) is divided by half to produce four haploid cells (cells with a single set of chromosomes), which develop to form gametes that are genetically to the parent cell that produced it. Meiosis takes place in all sexually reproducing unicellular and multicellular eukaryotes which includes animals, plants, and fungi. Sperm and eggs are the haploid cells made during meiosis in humans.

OD. The cells in these two areas have different DNA.
Answers
The different structures of cells in cross sections suggest that the different areas of the plant have different functions.
The presence of cells with very different structures in cross sections of different areas of the same plant suggests that the cells in these areas have different functions. Cells in different regions of a plant can specialize and differentiate to perform specific tasks essential for the plant's overall function. For example, cells in the root system may have adaptations for absorption and water transport, while cells in the leaf tissue may be specialized for photosynthesis. The variation in cell structures reflects their specific roles and adaptations to fulfill their respective functions. While options A, C, and D may be possibilities in certain contexts, the most reasonable and general conclusion based on the given information is that the cells in different areas of the plant have different functions.Therefore, the correct option is (B).For more such questions on Cells:

Answers
Answer:
a car:
Flagellum is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.
Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.
The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.
Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.
The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.
Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.
Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off
Explanation:
The internal structures found in a typical photosynthetic Euglena are as follows:
Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape
Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment
Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles
Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis
Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins
Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source
Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins
Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell
Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes
Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins
Contractile Vacuole: It maintains the water and salt balance within the cell
Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water
Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming
Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma
Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis
Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.
The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.
What is Euglena?Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.
What is flagellum?Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.
With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.

Therefore, the correct answer is:
a) Transcription (for copying genetic information from DNA to RNA)
b) Translation (for using the information contained in mRNA)
Copying inheritable information from DNA to RNA is a pivotal step in gene expression and is known as recap. Recap involves the conflation of a reciprocal RNA patch using one beachfront of the DNA as a template. The process of recap is carried out by an enzyme called RNA polymerase, which recognizes specific regions on the DNA called promoters and initiates the conflation of RNA.
During recap, the DNA double helix unwinds, and the RNA polymerase binds to the protagonist region. The enzyme also moves along the DNA template beachfront, adding reciprocal RNA nucleotides to the growing RNA chain. Adenine( A) dyads with uracil( U) in RNA, cytosine( C) dyads with guanine( G), and thymine( T) dyads with adenine( A) in DNA. This process continues until the RNA polymerase reaches a termination sequence, motioning the end of recap.

I know that Diuron caused the coral to bleach because the coral expelled the algae that are living in their tissues.
What is Diuron?This is referred to as a herbicide which is made up of substituted urea and it is used for the control of crop and noncrop areas. Its mechanism of function is that it is able to inhibit photosynthesis which prevents plant growth.
In a situation where corals bleach, they turn white which is as a result of them expelling algae in their tissues due to different types of stressful conditions. An exposure to chemicals or a high pH may result in this condition also.
In this scenario we were told that the coral bleached however diuron inhibits photosynthesis which could have caused the expulsion of the algae which is why it was chosen.

Striated muscles are so-called because of a repeating pattern of light and dark bands. One repeating unit of the banding pattern is called a sarcomere. sarcofibril. myomere. crossbridge. myofilament.
Answers
The term "striated muscles" is used to describe muscles that exhibit a distinctive pattern of alternating light and dark bands. These bands consist of repeating units known as sarcomeres. Hence the first option is correct.
Striated muscles: Striated muscles, also known as skeletal muscles, are a kind of muscle that is accountable for the voluntary movement of the human body's bones. They are also involved in maintaining and maintaining body posture.
The striations in skeletal muscles are caused by the precise alignment of contractile myofilaments within sarcomeres. These myofilaments are made up of the proteins actin and myosin and are responsible for muscle contraction.
Sarcomere: A sarcomere is the smallest functional unit of a muscle fiber. It is responsible for producing muscle contraction by shortening in response to an action potential, resulting in muscle contraction. A sarcomere is defined by two Z-discs, which are composed of proteins that anchor thin actin filaments.
The area between two Z-discs is called a sarcomere and is the basic unit of contraction in skeletal muscles. As a result of the overlapping arrangement of the actin and myosin filaments, the sarcomere appears striated.
